Title: Test equipment for engine
Inventor: OGISO TOMIO
IPC: G05B11/36
Filed: 1995-04-18
Abstract: PURPOSE: To perform sweep test of automobile engine without causing any hunting of throttle. CONSTITUTION: The r.p.m. of an automobile engine increases or decreases depending on a throttle opening command (g) and a detected r.p.m. (a) of engine is taken into a controlled. The throttle opening command (g) is determined such that the r.p.m. (a) of engine follows up a sweep command (b). In other words, the throttle opening command (g) is determined by integrating a difference/differentiation command (i) obtained by adding the differentiated value of engine r.p.m. to the difference between the sweep command (b) and the engine r.p.m. A limiter circuit 40 cuts the negative value of the difference/ differentiation command (i) to output only the positive value when the sweep command increases gradually otherwise outputs only the negative value.

Title: Optical communication apparatus
Inventor: ITOU KATSUYOSHI
IPC: H04B10/40
Filed: 1979-07-18
Abstract: PURPOSE:To reduce occurrence of both the signal distortion and the noise, by providing the light source having the laser diode LD which oscillates at a time and in the three wavelengths or more plus the optical fiber each. CONSTITUTION:The photosignal sent from LD100 which functions as the light source of light emitting part 10 is led into transmitting optical fiber 30 via optical connector A20. Fiber 30 is connected to another fiber 30 by optical connector 40 to transmit the photosignal and the photosignal is led to light receiving part 50 via optical connector 20. The LD which oscillates at one time and in plural numbers of wavelengths is used for the light source of part 10. As a result, the coherent length of the laser beam is decreased, and the contrast ratio of the speckle pattern is reduced suddenly as the optical fiber length increases. At the same time, the feedback optical amount from the specified reflecting point to each oscillation wave- length is reduced since the general optical amount is scattered to each oscillation wavelength, thus reducing the perturbation of the laser oscillation. Accordingly, both the signal distortion and the noise can be reduced.

IPC: H01J17/49
Filed: 1981-06-16
Abstract: PURPOSE: To stabilize the discharge work of a gas-discharge display device, and prevent any reduction of the luminance by connecting cells in groups so that the difference in discharge initiation voltage of discharge cells caused according to coupling capacity sent from an ion source becomes larger than the difference in discharge initiation voltage of discharge cells caused during the break down discharge.  
     CONSTITUTION: Display dicharge cells 3 are arranged in matrix form at a pitch of 1mm so that five cells 3 are arranged lengthwise and seven cells 3 are arranged sideways si as to constitute a character format. A display screen is constituted byarraging 32 thus constituted character formats sideways. In this example, only when the distance between scanning electrodes becomes above 20mm, the difference in discharge initiation voltage of discharge cells caused according to the coupling capacity sent from an ion source (the discharge cells of the discharge carried out before) becomes larger than the difference in discharge initiation voltage of discharge cells during break down condition. As a result, since the pitch of the cells 3 is 1mm, the discharge operation can be stabilized by connecting every above 20 scanning electrodes together, and adjusting the driving phase to above 20.

Title: Pressure control valve
Inventor: UDONO JIYUN
IPC: F16K17/04
Filed: 1980-07-08
Abstract: PURPOSE: To wholly make it compact and facilitate manufacturing the valve body and the piston in such a way that a back pressure chamber is formed by idly inserting a subpiston on the opposite side to the inlet side of the piston, in a direct-acting relief valve.  
     CONSTITUTION: When working liquid is fed through an inlet port 4 into a hydraulic chamber 11, the working liquid is filled through a passage 21 into a back pressure chamber 23. In result, liquid pressure is worked so that a piston 6 moves to the right from the transverse area of a piston 6 at the part where it is idly inserted to a cylinder 2 to the area subtracted the transverse area of a subpiston 22 at the part where it is idly inserted to a hole 20. When liquid pressure to move the piston 6 to the right becomes higher than impetus force of a resilient body 9, the piston 6 is moved to the right, and an outlet port 5 is opened. When liquid pressure on the hydraulic chamber 11 becomes lower, impetus force of the resilient body 9 makes the piston 6 move to the left and closes the outlet port 5. Thus, the determined value of the resilient body 9 can be diminished.

Title: Magnetic recording and reproducing system
Inventor: FURUYA NOBUAKI
IPC: G11B5/02
Filed: 1980-07-07
Abstract: PURPOSE:To realize an analog vertical magnetization recording of a high density, by varying the ratio of area of both the upward and downward magnetizing regions in proportion to the strength of the recording signal and with a fluctuation caused in the direction of the track width. CONSTITUTION:A recording medium 3 moves from the back to the surface of the paper, and the tip face of an auxiliary magnetic pole 2 is set oblique to a main magnetic pole 1 or the medium 3. As a result, the magnetic field formed between the pole 2 and the pole 1 or the medium 3 is uneven in the direction of the track width and is intensive at its right side. Thus the right side of the tip of the pole 1 is also magnetized intensively, and a magnetic layer 4 is magnetized upward like the pole 1. However, the left side of the tip of the pole 1 is magnetized weakly, and  the previous downward magnetization cannot be turned to the upward magnetization. When the signal current intensity flowing to a coil 2 is increased, a region  where the magnetization turns to the upward direction from the downward direction is increased to shift a boundary 9. Thus the area is decreased for a downward  magnetizing region 7'.
